[Paniraja Guptha, Akshay]

Hi Louise,
    Thanks for bringing this to our attention. We will take a look at the issue and get back to you.

Hi Mvapich-discuss, Compiling MVAPICH with LLVM based compilers - reproduced with Intel oneAPI compilers and Arm Compiler For Linux - is missing symbols for MPI_Status_f2c and MPI_Status_c2f. Example application to reproduce: ---------------------------------------------------#include

Hi Mvapich-discuss,

Compiling MVAPICH with LLVM based compilers - reproduced with Intel oneAPI compilers and Arm Compiler For Linux - is missing symbols for MPI_Status_f2c and MPI_Status_c2f.

Example application to reproduce:
---------------------------------------------------
#include "mpi.h"
#include <stdio.h>

int main(int argc, char* argv[])
{
    MPI_Init(&argc, &argv);

    MPI_Status_f2c(NULL, NULL);

    MPI_Finalize();
}
---------------------------------------------------

Compiled with:
---------------------------------------------------
 $ mpicc -g -O0 -o statusf2c statusf2c.c
/usr/bin/ld: /tmp/icx-a077a70d2b/statusf2c-f9cff4.o: in function `main':
/home/louspe01/test_dir/statusf2c.c:8: undefined reference to `MPI_Status_f2c'
icx: error: linker command failed with exit code 1 (use -v to see invocation)

 $ mpicc -v
mpicc for MVAPICH version 3.0
Intel(R) oneAPI DPC++/C++ Compiler 2024.1.0 (2024.1.0.20240308)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: intellinstalldir/compiler/2024.1/bin/compiler
Configuration file: intellinstalldir/compiler/2024.1/bin/compiler/../icx.cfg
Found candidate GCC installation: /usr/lib/gcc/x86_64-linux-gnu/10
Found candidate GCC installation: /usr/lib/gcc/x86_64-linux-gnu/11

---------------------------------------------------

Similarly for MPI_Status_c2f the symbol is missing.

The configure line for MVAPICH was:
---------------------------------------------------
Configuring MVAPICH version 3.0 with  '--enable-debug' '--enable-debuginfo' '--enable-shared' '--with-device=ch3:sock' 'F90=' '--prefix=mvapichinstalldir' '--bindir=${prefix}/bin' '--sbindir=${prefix}/bin' '--libexecdir=${prefix}/bin' '--libdir=${prefix}/lib' '--includedir=${prefix}/include' '--oldincludedir=${prefix}/include' '--datarootdir=${prefix}/share' 'CC=icx' 'CFLAGS=' 'LDFLAGS=' 'LIBS=' 'CPPFLAGS=' 'CXX=icpx' 'CXXFLAGS=' 'FC=ifx' 'F77=ifx'
---------------------------------------------------

All the best,
